vdub. the parts breakdown for your wheel should be in your repair manual.You do have a repair manual don't you?
The Clymer page 134 shows the early models, the one used before they started bolting the rotors on the hub, but they are similar. Places like boats.net have parts fiches that show all the parts and the order they go.
They only show a complete breakdown the first year of an assembly, after that they just show changes. So for a 74 up front wheel it only shows the 74 break down. They didn't change it until the mags came out.
If you don't find the breakdown for your year just back up year by year till you find it.
